Lette/rs Patent No. 96,113, dated October 26,1869.

IMPROVED IMPLEMENT FOR LAYiING- WOOD PAVEMENT.

The Schedule referred to in these Letters Patent -and making part of the same. l

To all whom z't may concern Be it known that I, PHILIP HINKLE, of San Francisco, in the county of San Francisco, and State of California, have invented an Improved Implement for Laying Vood Pavement; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention is to provide an improved implement to be employed in the construction of wood or block pavements, so that the space between each block or row of blocks will be uniform in width, and on a straight line from curb to curb, and the interstices be packed with sand or rubble, for binding and holding the blocks to the foundation or bed upon which they rest.

Referring to the drawings- Figure 1 is a plan or top view of' the pavement and implement.

Figure 2 is a transverse view of pavement, showing a back view of the implement resting on the two end blocks, with tamping-bar broken ofi'.

Figure 3 is a longitudinal section of the pavement and implement, with camping-bar.

A represents a thin strip of metal, or wood, set on edge, and to the front portion of' which is attached a piece of metal, B, bent at right angles outwardly, and when in position, rests on the preceding row of blocks.

To the back part 'of the vertical gauge-board, at each end, are attached lugs, C C, bent at the same angle, and opposite the piece B.

A s'ucient space, D, is formed between these guides, by vertical posts E EE, to which they are riveted. The space D is suicient to admit the tamping-bar, by which the filling can be rammed before the gauge is removed.

In the bottom of the space is placed sand, which is tamped with the tamping-b'ar F, and when a suficient height from the foundation is attained, the remaining space is filled with rubble, or other material.

In this connection, however, it will he well to state that after the first gauge is employed, and the first row of pavement laid, the second gauge should be pressed against the pavement, heretofore referred to,

to keep the blocks in position, before the tamping of i the first he performed; consequently two gauges ymust be employed, and be moved forward alternately.

By this means a true gauge is had, and every block may bc set true, lengthwise and transversely,l f'rorn curb to curb of' the street, without keys or wedges.

Having thus described my invention,

The gauge described, consisting of the vertical strip A, bent plate B, lugs C C, and posts E E, when ar-` and seal.
